'Blonde' star Ana de Armas says she was haunted by Marilyn Monroe on set

• "Blonde" star Ana de Armas said the set was haunted by Marilyn Monroe.
• She told Reuters that she felt the Hollywood star's spirit on set and thought she was "happy."

"Blonde" star Ana de Armas said that she felt the ghost of Marilyn Monroe while filming the new Netflix biopic.

de Armas plays the Hollywood icon in the upcoming movie, which premiered at Venice Film Festival Thursday.

At the premiere of the movie, the 34-year-old actress told reporters that she felt the presence of Monroe on set, according to Reuters.

"I truly believe that she was very close to us. She was with us," de Armas said. "I think she was happy. She would also throw things off the wall sometimes and get mad if she didn't like something. Maybe this sounds very mystical, but it is true. We all felt it."

de Armas added later: "She was all I thought about, she was all I dreamt about, she was all I could talk about, she was with me and it was beautiful."

Last year, de Armas told The Sunday Times of London that it took a long time to match Monroe's infamous bubbly voice for the movie.

"I tried!" de Armas said. "It only took me nine months of dialect coaching, and practicing, and some [automated dialogue replacement] sessions. It was a big torture, so exhausting. My brain was fried."

Andrew Dominik, who directed the movie, told reporters at Venice Film Festival that he was convinced de Armas could play the role, despite her strong Spanish accent, after seeing her in the 2015 film "Knock Knock."

"I knew it was her as soon as I saw her on TV. It is a little bit like when you fall in love at first sight, when the right person walks through the door you know it," he said, according to Reuters.

According to Variety, de Armas was in tears during the 14-minute standing ovation following the Venice premiere screening of "Blonde."

"Blonde" premieres on Netflix on September 28.
